Simplifying subtitle display processing in a variable speed reproduction mode on the receiving side is intended. A video stream formed with a video packet having coded image data in a payload is generated. A subtitle stream formed with a subtitle packet having subtitle information in a payload is generated. A multiplexed stream including the video stream and the subtitle stream is generated and transmitted. In generating the multiplexed stream, the subtitle packet is arranged at a random access position.

Rights management and syndication of content

Systems, devices, and methods are described herein for distributing syndicated content or content with one or more distribution restrictions. In one aspect, a method may include assigning a unique ID to a plurality of content items, where the unique ID of at least one of the content items is associated with one or more property distribution restrictions. The method may further include streaming in a video stream the content items to at least two properties and monitoring the unique IDs of the plurality of content items streamed in the video stream to detect least one content item associated with the one or more property distribution restrictions. The distribution of the least one content item associated with the one or more property distribution restrictions may be blocked from the one or more properties concurrently with streaming the video stream, based on the one or more property distribution restrictions.

Break state detection for reduced capability devices

Systems, methods, and devices are described herein for placing secondary content into a break of unknown duration in a stream of primary content. In one aspect, the described techniques may include streaming a segment of primary content, for example, by a reduce capability client device, such as a mobile device or tablet. The device may receive information indicative of a break in the streaming of the primary content. The device may play secondary content based on receiving the information indicative of the break. The device may determine when a next segment of the primary content is available, and begin streaming the next segment of the primary content upon detecting that the second segment of the primary content is available.

Content Segmentation and Time Reconciliation

Systems, devices and methods are described herein for segmentation of content, and more specifically for segmentation of content in a content management system. In one aspect, a method may include receiving content associated with speech, text, or closed captioning data. The speech, the text, or the closed captioning data may be analyzed to derive at least one of a topic, subject, or event for at least a portion of the content. The content may be divided into two or more content segments based on the analyzing. At least one of the topic, the subject, or the event may be associated with at least one of the two or more content segments based on the analyzing. At least one of the two or more content segments may then be published such that each of the two or more content segments is individually accessible.

APPARATUS AND METHODS FOR LATENCY REDUCTION IN DIGITAL CONTENT SWITCHING OPERATIONS
20190069004 · 2019-02-28 ·

Apparatus and methods for reducing latency in content and content source switching in a digital content delivery network. In one embodiment, linear addressable secondary content is switched into primary content within a cloud-based model using one or more latency-reducing techniques so as to minimize the user's perception of delay in performing the switch. In one implementation, secondary content video encodings are selected based on the encoding scheme of the primary content, and open GOPs within the primary content at the content transition point are closed or avoided, each to reduce processing overhead of the recipient client device. In another implementation, otherwise cloud-inaccessible functionality of the client device is accessed to reduce or suspend processing on non-essential tasks to make more processing resources available at the client. In yet another implementation, intelligent RF PHY scheduling of the primary and secondary content are utilized to minimize RF re-tuning by the client.

APPARATUS AND METHOD FOR PROVIDING STREAMING CONTENT USING REPRESENTATIONS

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. Each of the periods may include one or more representations. The metadata may include information used to describe a relationship between the representations, and include information for terminals having different display bit depth.
